The drawback is that the multi cross loses tension pretty fast. But I'm not sure if that's a problem since polys lose tension quickly anyway, which might be a good match. One of these times I'll pre-stretch the Hexy Fiber and see how that feels.

I get a lot of feel and a lot more spin than I thought I'd get from a smooth poly. The shape of the Hexy Fiber may contribute to the low friction between the two strings, promoting extra spin. It's a theory.

Thanks to the overall low tension the frame has lost only 0.2mm of length.

I change crosses after 5 hours of playing because it lose very fast elasticity. But I can suppose any medium softness poly would work with this setup, maybe something that would last more will be better but at this moment I'm stick with this setup(pro's pro string is very very cheap, and I change TB mains only after 10-15 hours)

2. Pros: Great feel at net, power on serve, depth on groundstrokes, easy on arm. Cons: Price, not as much access to spin as with pure ALU Power Rough.

I have two Speed Pros, one Speed MP, and two Prestige MPs. I split each racquet "set" into one hybrid and one ALU Power Rough, and the Speed MP is the odd man out, but it usually gets hybrid because of the open pattern.

Not sure what it is that I like about this set up but it is not too expensive as lux is a lot cheaper than it used to be and Gosen is really well priced. The other thing is the Gosen breaks just as I feel that the lux is going dead. Which is perfect because I don't like cutting out a string job and I don't like playing with a dead bed either so this timing is perfect( for me)

Graphene Speed MP w/ Cyclone 1.25 and Volkl SG 1.25 56/44. VSG is quite firm for a SG, very slippery too. Crosses break in about 5 hours which is fine because then I don't have to worry about cutting them out when the Cyclone is mushy and dead. IMO Cyclone is medium firm and medium powered for a poly. Great spin setup.

crosses: still looking but have used natural gut, prince syngut with duraflex, ashaway zx, and dynamite 18 blue all at 32lb.

Pros: I like a stiff string bed and a "board" feel. At 32lbs the kevlar still gives that. The crosses add some give and playability so there is some ball pocketing which a new thing that I am liking. Kevlar and low tension lets me use 18g so it should get more spin. Kevlar will probably never break and strings can last especially if I use 18g at for the crosses. Arm is happy and I still have a control racket.

Cons: People on message boards think you are nuts, for using kevlar, and super low tension.

Currently using Pro Hurricane Tour mains @48 crossed with xcel @53. Really nice playing and very comfy actually for a poly hybrid. Not overly spinny, but a more heavy ball generator because it gives a bit of free power too. Very nice setup. Gonna see how long it lasts until it starts bugging my arm/shoulder.

So the pros are: good power spin and control blend, soft for now.

Cons: none yet except slightly pricey. Might be worth it in the long run though.

One low-cost and durable hybrid I used to have in a six one 95 18x20 was Luxilon Adrenaline 16 at 58 in the mains, and Wilson Stamina at 60 in the crosses. It was fairly stiff and the power level stayed fairly consistent because as the poly got more pop to it the stamina started to die down some... very solid and consistent stringbed, not the most feel though.
